A male of the bee genus Agapostemon in Dominican amber (Hymenoptera: Halictidae)
(University of Kansas, 2013-09-04)The first fossil species of the caenohalictine bee genus Agapostemon Guérin-Méneville (Halictinae: Caenohalictini:Agapostemonina) is described and figured from a single male preserved in EarlyMiocene (Burdigalian) amber ... -
First record of Chiasmognathus from the Kingdom of Saudi Arabia (Hymenoptera, Apidae)
(Pensoft Publishers, 2013-10-25)The cleptoparasitic bee genus Chiasmognathus Engel (Nomadinae: Ammobatini) is recorded from Saudi Arabia for the first time. Chiasmognathus nearchus Engel was previously known from specimens collected in the United Arab ... -
Mesozoic giant fleas from northeastern China (Siphonaptera): Taxonomy and implications for palaeodiversity
(SpringerOpen, 2013-05)The recently discovered definite giant fleas from the Middle Jurassic Daohugou fauna and the Early Cretaceous Jehol fauna of northeastern China represent significant evidence for understanding ectoparasitism in the Mesozoic ... -
A new trap-jawed ant (Hymenoptera: Formicidae: Haidomyrmecini) from Canadian Late Cretaceous amber
(Cambridge University Press, 2013-05-15)A new genus and species are described within the extinct tribe Haidomyrmecini, and tentatively placed within the subfamily Sphecomyrminae (Hymenoptera: Formicidae). Haidoterminus cippus new genus and species expands the ... -
Wasp mimicry among Palaeocene reduviid bug from Svalbard
(Polska Akademia Nauk, Instytut Paleobiologii, 2013)The enigmatic Svalbard Palaeocene fossil taxon Hymenopterites deperditus is revised, and is neither a wasp nor a plant seed, but turns out to be a bug hemelytra corresponding to the oldest described reduviid bug. It can ... -
A termite from the Late Oligocene of northern Ethiopia
(Polska Akademia Nauk, Instytut Paleobiologii, 2013)Termites of the family Stolotermitidae are a relict lineage of primitive Isoptera. The fossil record of Stolotermitidae is exceptionally poor, with only two Miocene (Neogene) species documented to date. Herein, a new genus ... -
Contributions to the systematics, comparative morphology, and interrelationships of selected lecanicephalidean tapeworms (Platyhelminthes: Cestoda: Lecanicephalidea)
(University of Kansas, 2013-05-31)The Lecanicephalidea (Platyhelminthes: Cestoda) are a morphologically diverse group of elasmobranch (Chondrichthyes: Elasmobranchii) tapeworms. Currently, 95 species in 16 genera are recognized as valid. However, nine ... -

Dynamic homology and phylogenetic systematics: a unified approach using POY
(American Museum of Natural History, 2006) -
The question of sex identification in specimens housed in research collections
(OMICS Publishing Group, 2012-12) -
Temporal Patterns of Diversification across Global Cichlid Biodiversity (Acanthomorpha: Cichlidae)
(Public Library of Science, 2013-08-19)The contrasting distribution of species diversity across the major lineages of cichlids makes them an ideal group for investigating macroevolutionary processes. In this study, we investigate whether different rates of ... -
Species-specific bioluminescence facilitates speciation in the deep sea
(Springer US, 2014-05)The vast darkness of the deep sea is an environment with few obvious genetic isolating barriers, and little is known regarding the macroevolutionary processes that have shaped present-day biodiversity in this habitat. ... -
Mitochondrial Intergenic Spacer in Fairy Basslets (Serranidae: Anthiinae) and the Simultaneous Analysis of Nucleotide and Rearrangement Data
(American Museum Novitates, 2009-07)We present the results of a study that implements a recently developed phylogenetic algorithm that combines fixed-states nucleotide optimization with breakpoint analysis to identify and examine the evolution of a mitochondrial ... -
From taxonomic literature to cybertaxonomic content
(Biomed Central, 2013-10-31) -
Genome-level homology and phylogeny of Vibrionaceae (Gammaproteobacteria: Vibrionales) with three new complete genome sequences
(Biomed Central, 2013-04-11)Background Phylogenetic hypotheses based on complete genome data are presented for the Gammaproteobacteria family Vibrionaceae. Two taxon samplings are presented: one including all those taxa for which the genome sequences ... -
Clade Age and Diversification Rate Variation Explain Disparity in Species Richness among Water Scavenger Beetle (Hydrophilidae) Lineages
(Public Library of Science, 2014-06-02)Explaining the disparity of species richness across the tree of life is one of the great challenges in evolutionary biology. Some lineages are exceptionally species rich, while others are relatively species poor. One ... -
A High-Resolution Genetic Map of Yellow Monkeyflower Identifies Chemical Defense QTLs and Recombination Rate Variation
(Genetics Society of America, 2014-05-04)Genotyping-by-sequencing methods have vastly improved the resolution and accuracy of genetic linkage maps by increasing both the number of marker loci as well as the number of individuals genotyped at these loci. Using ... -
Invasive potential of cattle fever ticks in the southern United States
(Springer, 2014-04-17)Background For >100 years cattle production in the southern United States has been threatened by cattle fever. It is caused by an invasive parasite-vector complex that includes the protozoan hemoparasites Babesia bovis ... -
